> The concrete driveway cost calculator estimates the concrete, gravel base, reinforcement, forms and labour for a new concrete driveway and gives the total and cost per square foot.

## Inputs

- Driveway length (ft, m, in, yd, cm)
- Driveway width (ft, m, in, yd, cm)
- Concrete thickness (in, cm, mm, ft, m)
- Concrete waste (%)
- Gravel base depth (in, cm, mm, ft, m)
- Concrete price (/yd³, /m³, /ft³)
- Gravel price (/US ton, /t, /lb, /kg)
- Reinforcement (mesh or rebar) price (/ft², /m², /yd²)
- Forms price (/ft, /m, /yd)
- Labour and finishing (/ft², /m², /yd²)

## Results

- Driveway area
- Concrete
- Gravel base
- Concrete cost
- Gravel cost
- Reinforcement cost
- Forms cost
- Labour cost
- Total cost
- Cost per area

## Formula

```
Concrete = L × W × thickness × (1 + waste)
Gravel = L × W × base depth × 1.2 (compaction) × density
Cost = concrete + gravel + reinforcement × area + forms × perimeter + labour × area
```

## Explanation

A concrete driveway lasts 30 years or more when it sits on a compacted gravel base, is at least 4–5 in thick (6 in for heavy vehicles) and is reinforced with wire mesh, fibre or rebar. Material is usually less than half the total; labour for excavation, forming, placing and finishing makes up the rest.

### How to use the Concrete Driveway Cost Calculator

- **Driveway length**
- **Driveway width**
- **Concrete thickness**
- **Concrete waste**
- **Gravel base depth**
- **Concrete price**
- **Gravel price**
- **Reinforcement (mesh or rebar) price**
- **Forms price**
- **Labour and finishing**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the driveway dimensions and thickness, the base depth and unit prices for concrete, gravel, reinforcement, forms and labour. The calculator works out each quantity and cost.

### Tips for an accurate estimate

- Plan driveways and paths in layers – a compacted base of larger stone does most of the structural work.
- Add 10–25% for compaction: loose stone shrinks once it is rolled or driven on.
- Ask the quarry whether prices are per US ton, metric tonne or cubic yard before comparing quotes.
- Grade surfaces at 1–2% so water runs off rather than soaking into the base.

### Common mistakes to avoid

- Skipping the base layer or geotextile on soft soil, which leads to ruts and potholes.
- Using rounded stone (pea gravel, river rock) on surfaces that carry vehicles.
- Ordering compacted volume when the supplier delivers loose material.

### What each result means

- **Driveway area** = [Driveway length]×[Driveway width]
- **Concrete** = [Driveway length]×[Driveway width]×[Concrete thickness]×(1 + [Concrete waste]÷100)
- **Gravel base** = [Driveway length]×[Driveway width]×[Gravel base depth]×1.2×1602
- **Concrete cost** = [Concrete]×[Concrete price]
- **Gravel cost** = [Gravel base]×[Gravel price]
- **Reinforcement cost** = [Driveway area]×[Reinforcement (mesh or rebar) price]
- **Forms cost** = 2×([Driveway length] + [Driveway width])×[Forms price]
- **Labour cost** = [Driveway area]×[Labour and finishing]
- **Total cost** = [Concrete cost] + [Gravel cost] + [Reinforcement cost] + [Forms cost] + [Labour cost]
- **Cost per area** = [Total cost]÷[Driveway area]

### Example values

## Worked example

Inputs — Driveway length: 40 ft; Driveway width: 12 ft; Concrete thickness: 5 in; Concrete waste: 5 %; Gravel base depth: 4 in; Concrete price: $150 /yd³; Gravel price: $35 /US ton; Reinforcement (mesh or rebar) price: $0.5 /ft²; Forms price: $2 /ft; Labour and finishing: $4 /ft².

Results — Driveway area = 480 ft²; Concrete = 7.78 yd³; Gravel base = 9.6 US ton; Concrete cost = $1,166.67; Gravel cost = $336.03; Reinforcement cost = $240.00; Forms cost = $208.00; Labour cost = $1,920.00; **Total cost = $3,870.70**; Cost per area = $8.06 /ft².

## FAQ

**How much does a concrete driveway cost?**
Typically $8–$15 per ft² installed in the U.S., depending on thickness, finish and access.

**How thick should a concrete driveway be?**
4 in minimum for cars, 5 in is better, and 6 in for trucks, RVs or poor soils.

**Do I need rebar in a driveway?**
Wire mesh or fibre is common for residential drives; rebar (#3 or #4 at 18–24 in) adds crack resistance.

**What formula does the Concrete Driveway Cost Calculator use?**
Concrete = L × W × thickness × (1 + waste).
